Casing standards.
(d) New or used plain end casing, except when
being used as conductor pipe, that is welded together
for use must meet the following requirements:
(1)
The
casing must pass a pressure test by holding the anticipated maximum pressure to
which the casing will be exposed for 30 minutes with not more than 10% decrease
in pressure. The operator shall notify
the Department at least 24 hours before conducting the test. The test results shall be entered on the
drilling log.
Question:
Is pressure testing for welded surface casing
necessary when a second string of casing is run?
Response:
All welded casing strings, aside from the
conductor pipe, must be pressure tested.
Well construction details have no bearing on this requirement.
